• Voltage: 600V
• Terminal Material: Pure copper with tin plating
• Barrel Construction: Brazed barrel for uniform crimping and vibration resistance
• Automotive & Marine Battery Systems - Splice starter cables, alternator feeds, and battery bank connections in vehicles and boats where nylon insulation prevents accidental shorts while providing superior durability against vibration, moisture, and temperature extremes in demanding underhood and bilge environments.
• Heavy Equipment & Machinery Power Feeds - Join motor cables, power distribution conductors, and equipment feeds in industrial machinery, construction equipment, and agricultural vehicles where high-current splices require durable insulation and vibration resistance for reliable long-term performance.
• RV & Trailer High-Current Systems - Splice inverter cables, solar charge controller wiring, and 12V distribution feeds in recreational vehicles where nylon insulation provides color-coded identification and prevents shorts in tight compartments with multiple high-amperage connections.
• Outdoor Power Equipment & Generators - Connect power cables for portable generators, welding equipment, and outdoor machinery where nylon insulation protects against environmental exposure while maintaining secure splices under high-vibration operating conditions.
